Background
With the rapid development of terminal technology, editing objects such as pictures and characters becomes a basic function of a terminal, a user can edit the objects through the terminal, for example, rotating and amplifying the pictures, and when the user thinks that the operation recently completed by the user is a misoperation or thinks that the operation does not reach the desired effect, the user can cancel the completed operation, so that the object corresponding to the operation is restored to the state before the operation.
The commonly used operation revocation method is as follows: when the terminal receives the withdrawal instruction, the terminal executes reverse operation on the object which finally enters the stack from the stack for storing the object so as to realize the withdrawal of the operation.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
An embodiment of the present invention provides an operation revocation method, and referring to fig. 1, the method includes:
step 101: when an operation cancel instruction of a first object is detected, a second object is determined based on an object identifier of the first object, the first object is obtained by displaying the second object at a first display position after the second object is subjected to editing operation, and the first object is any one object displayed in a current page.
It should be noted that the operation canceling instruction may be triggered by a user currently using the terminal through a specified operation, where the specified operation may be a click operation on the first object, a sliding operation on a preset track, or the like.
In addition, when the terminal creates the second object, an object identifier may be assigned to the second object, and since the first object is obtained after the editing operation is performed on the second object, the first object and the second object are substantially represented by objects with the same content in different states, for example, when the second object is a picture 1, and the editing operation is an enlarging operation, the first object obtained after the enlarging operation is performed on the picture 1 of the second object is an enlarged picture 1, that is, the content of the first object and the content of the second object are the same, but the states are different, that is, the sizes are different. Since the first object and the second object are substantially the same content of the object in different states, when the first object is obtained after the terminal performs the editing operation on the second object, the object identifier of the first object may be assigned to the second object, that is, the object identifiers of the first object and the second object are the same. The object id may be a set of numerical sequence numbers, for example, the object id of the first object may be 1, 0001, and so on.
Further, the editing operation may include an enlargement operation, a reduction operation, a rotation operation, a display position movement operation, a font color change operation, and the like.
The terminal determines, based on the object identifier of the first object, the implementation manner of the second object, which may be the following two manners:
the first determination method: and acquiring the object positioned at the top of the stack from the object stack corresponding to the object identifier, and determining the acquired object as a second object, wherein the object stack is used for storing the objects in different editing operation states.
In the object stack corresponding to the object identifier, the terminal may sequentially arrange the objects in different editing operation states from the stack bottom to the stack top according to the time for executing the editing operation, that is, the object located at the stack bottom is an object in an unedited state, that is, the object with the earliest time for the editing operation, and the object located at the stack top is an object with the latest time for the editing operation. Because each object identifier corresponds to one object stack, the terminal can cancel the editing operation performed on the object selected by the user according to the object identifier of the object selected by the user through the designated operation.
For example, the first object displayed in the current page may be picture 4, the object identifier of picture 4 may be 0001, the object stack corresponding to object identifier 0001 may be a stack as shown in table 1 below, in the object stack of 0001, picture 1 may be an object whose time for performing an editing operation on picture 4 is the earliest, that is, an initially created object corresponding to picture 4, picture 2 may be obtained after performing an enlargement operation on picture 1, picture 3 may be obtained after performing a rotation operation on picture 2, and picture 4 may be obtained after performing a reduction operation on picture 3, so that the terminal may determine picture 3 located at the top of the stack from the object stack of 0001 as the second object, that is, the object that is edited most recently before determining picture 4.
TABLE 10001 object Stack
In the embodiment of the present invention, only the object stack shown in table 1 is used as an example for description, and table 1 does not limit the embodiment of the present invention.
Further, when the terminal determines the second object according to the first manner, before detecting the operation cancel instruction of the first object, the terminal may further perform the following step (1) including: when the editing operation of the second object is detected, the editing operation is executed on the second object to obtain a first object; determining a first display position, and displaying a first object at the first display position; after the first object is displayed, the second object is stored at the top of the stack of objects corresponding to the object identifier.
The second determination method is as follows: and based on the object identification of the first object, acquiring an object with the operation time closest to the current time from the stored object identification, the corresponding relation between the operation time and the object, and determining the acquired object as a second object.
When the user needs to cancel the editing operation on a certain object, it may be considered that what the user wants to cancel at this time is an editing operation that is executed on the object most recently, and therefore, the terminal may also determine, by the second determination method, the second object, that is, the object that is determined to be in a state before the most recent editing operation. In addition, since the corresponding relationship between the object identifier, the operation time, and the object stores the operation time for performing the editing operation on each object, when the user currently using the terminal does not select an object, that is, when the terminal detects an operation cancel instruction that is not directed to any object, it may be considered that the user only wants to cancel the most recently performed operation, and at this time, the terminal may directly acquire the object whose operation time is closest to the current time from the stored corresponding relationship between the object identifier, the operation time, and the object, and determine the acquired object as the second object.
For example, the current time may be 2016.01.01.10:02:00, the first object may be a picture 014, the object identifier of the first object may be 0001, the correspondence between the object identifier and the operation time stored in the terminal and the object may be as shown in table 2 below, and the terminal may obtain an object picture 013 having the operation time closest to the current time 2016.01.01.10:02:00 from the correspondence between the object identifier and the operation time and the object as shown in table 2 below based on the object identifier 0001 of the first object picture 014 and determine the obtained object picture 013 as the second object.
TABLE 2
| Object identification | Time of operation | Object |
| 0001 | 2016.01.01.09:59:00 | Picture 011 |
| 0001 | 2016.01.01.10:00:00 | Picture 012 |
| 0001 | 2016.01.01.10:00:45 | Picture 013 |
| 0002 | 2016.01.01.10:01:13 | Picture 021 |
| …… | …… | …… |
In the embodiment of the present invention, only the correspondence between the object identifier, the operation time, and the object shown in table 2 above is taken as an example for description, and table 2 above does not limit the embodiment of the present invention.
Further, when the terminal determines the second object according to the second manner, before detecting the operation cancel instruction of the first object, the terminal may further perform the following step (2) including: when the editing operation of the second object is detected, the editing operation is executed on the second object to obtain a first object; determining a first display position, and displaying a first object at the first display position; after the first object is displayed, the object identification, the operation time for performing the editing operation on the second object and the second object are stored in the corresponding relation among the object identification, the operation time and the object.
In practical applications, the terminal may further set a pointer for the first object, where the pointer may point to a physical address of the second object, and then the terminal may directly obtain the second object based on the pointer of the first object. In addition, the terminal may further set the second object as a member variable of the first object after the first object is obtained by performing an editing operation on the second object, and then the terminal may directly obtain the member variable of the first object as the second object based on the first object. The manner of setting the pointer and the member variable may refer to related technologies, which are not described in detail in the embodiments of the present invention.
Further, after the terminal performs the editing operation on the second object in step (1) or step (2) to obtain the first object, any one of the following steps (3) and (4) may also be performed.
And (3): comparing the editing operation performed on the second object with the operations in the stored first-class operation list and the second-class operation list to determine whether the editing operation belongs to the first-class operation or the second-class operation; and when the editing operation belongs to the second type of operation, storing the object identification, the second object and the second display position of the second object in the corresponding relation among the object identification, the object and the display position.
Wherein the first type of operation is an operation of not changing the display position of the object, and the first type of operation may include an enlargement operation, a reduction operation, a rotation operation, a change font color operation, a highlight operation, and the like. The second type of operation is an operation of changing the display position of the object, and may include a display position moving operation or the like.
When the terminal performs the step (3), if the editing operation belongs to the first class of operation, the terminal may determine that the display positions of the first object and the second object are the same, and at this time, the terminal may not perform any operation, and if the editing operation belongs to the second class of operation, the terminal may determine that the display positions of the first object and the second object are different, and at this time, the terminal may store the object identifier of the second object, and the second display position in the correspondence relationship between the object identifier, the object, and the display position, so that when the editing operation is undone, the second display position may be obtained from the correspondence relationship.
And (4): and storing the object identification, the second object and the second display position of the second object in the corresponding relation among the object identification, the object and the display position.
When the terminal executes the step (4), the terminal does not need to distinguish whether the editing operation belongs to the first type of operation or the second type of operation, that is, no matter whether the editing operation belongs to the first type of operation or the second type of operation, the terminal can directly store the object identifier, the second object and the second display position of the second object in the corresponding relationship among the object identifier, the object and the display position, and at this time, the second display position may be the same as the first display position, that is, in the case that the editing operation belongs to the first type of operation, the second display position may also be different from the first display position, that is, in the case that the editing operation belongs to the second type of operation.
In addition, after the terminal performs an editing operation on the second object to obtain the first object, the first object may be stored in a latest state list, where the latest state list is used to store each object displayed in the current page, that is, an object in the latest state in the objects corresponding to each object identifier, and when the terminal is suddenly powered off or needs to restore the current page, the terminal may also display each object stored in the latest state list on the screen to restore the current page.
Further, before performing the step (1) or the step (2), the terminal may further perform the following steps, including: when an object creating instruction of a third object is detected, displaying the third object at a third display position, wherein the third display position is a display position carried by the object creating instruction; allocating an object identifier for the third object; and storing the object identification, the third object and the third display position of the third object in the corresponding relation among the object identification, the object and the display position.
The third object is an object corresponding to the first object and in an initial state, that is, the terminal first creates the third object, then performs a certain editing operation on the third object to obtain the second object, and then performs a certain editing operation on the second object to obtain the first object.
It should be noted that, when the object identifier of the third object is the third object created by the terminal, the object identifier allocated to the third object is used to distinguish the third object from other objects displayed in the current page, that is, the terminal may allocate different object identifiers to each object in the current page, so that the corresponding object may be determined according to the object identifiers.
Step 102: a second display position is determined, the second display position being a position at which the second object is displayed in the current page before the first object is displayed.
When the terminal performs the editing operation on the second object in step (1) or step (2) to obtain the first object and then performs step (3), the manner of determining the second display position by the terminal may be: when the editing operation belongs to a first type of operation, determining the first display position as a second display position; and when the editing operation belongs to the second type of operation, acquiring a second display position from the stored corresponding relation among the object identification, the object and the display position based on the object identification and the second object.
When the editing operation performed on the second object belongs to the first type of operation, the terminal may determine that the display position of the second object is not changed when the editing operation is performed on the second object, that is, the display positions of the first object and the second object obtained after the editing operation is performed on the second object are the same, and therefore, the terminal may directly determine the first display position as the second display position.
When the editing operation performed on the second object belongs to the second type of operation, the terminal may determine that the display position of the second object is changed when the editing operation is performed on the second object, that is, the display positions of the first object and the second object obtained after the editing operation is performed on the second object are different, and therefore, the terminal needs to obtain the second display position from the stored object identifier, the corresponding relationship between the object and the display position.
When the terminal performs the editing operation on the second object in step (1) or step (2) to obtain the first object, and then performs step (4), the terminal may determine the second display position by: and acquiring a second display position from the stored corresponding relation among the object identification, the object and the display position based on the object identification and the second object.
Step 103: and deleting the first object displayed at the first display position in the current page, and displaying the second object at the second display position to cancel the operation.
When the terminal needs to cancel the editing operation on the second object, the first object is considered not to be the object that the user wants to obtain, and the terminal does not need to display the first object at this time, so that the terminal can delete the first object displayed at the first display position in the current page. When the terminal needs to cancel the editing operation on the second object, it may be considered that the user wants to obtain the second object before the editing operation is performed, so the terminal may display the second object at the second position, that is, display the object before the editing operation is performed at the position before the editing operation is performed, thereby canceling the operation on the second object.
In the embodiment of the invention, when the operation cancel instruction of the first object is detected, the second object, namely the object in the state before the editing operation, can be determined based on the object identification of the first object, and because the second object can be stored locally in advance, the terminal can directly determine the second object based on the object identification of the first object without performing the inverse operation on the first object to obtain the second object, and because the inverse operation is not required to be performed, the time for canceling the operation is shortened, and the efficiency of the canceling operation is improved. Since the first object may be any object displayed in the current page, the operation cancelling instruction may be an operation cancelling instruction for any object in the current page, that is, the user may cancel an object that the user wants to cancel, instead of only canceling an editing operation corresponding to an object that has recently performed an editing operation, thereby increasing flexibility of the cancelling operation.
